microblaze: Fix copy_to_user_page macro

2010-08-04T08:22:31Z

copy_to_user_page macro is used in mm/memory.c:access_process_vm function. This function is called from ptrace code (POKETEXT, POKEDATA) which write data to memory. Microblaze handle physical address for caches that's why there is virt_to_phys conversion. There is potential one location which can caused the problem on WB system. The important is take a look at write PTRACEs requests (POKE/TEXT, DATA, USR). Note: Majority of Microblaze PTRACE code is moved to generic location in newer kernel version that's why this solution should work on the newest kernel version too. linux/io.h is in cacheflush because of mm/nommu.c Tested on a WB system - hello world debugging.

microblaze: Implement flush_dcache_page macro

flush_dcache_page macro is necessary to implement for JFFS2 rootfs support on WB system. Signed-off-by: Michal Simek

microblaze: Support for WB cache

2009-12-14T07:45:10Z

Microblaze version 7.20.d is the first MB version which can be run on MMU linux. Please do not used previous version because they contain HW bug. Based on WB support was necessary to redesign whole cache design. Microblaze versions from 7.20.a don't need to disable IRQ and cache before working with them that's why there are special structures for it. Signed-off-by: Michal Simek

block: add helpers to run flush_dcache_page() against a bio and a request's pages

2009-11-26T08:16:19Z

Mtdblock driver doesn't call flush_dcache_page for pages in request. So, this causes problems on architectures where the icache doesn't fill from the dcache or with dcache aliases. The patch fixes this. The ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE symbol was introduced to avoid pointless empty cache-thrashing loops on architectures for which flush_dcache_page() is a no-op. Every architecture was provided with this flush pages on architectires where ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE is equal 1 or do nothing otherwise. See "fix mtd_blkdevs problem with caches on some architectures" discussion on LKML for more information. Signed-off-by: Ilya Loginov Cc: Ingo Molnar Cc: David Woodhouse Cc: Peter Horton Cc: "Ed L.
